My sister tried to print something from her wireless printer and it successfully printed. However, the images that were printed as well as some other images ended up automatically downloading on my mom's computer.

I think they might be connected to the same printing network, but is this normal? How do you disable this from happening so that the images don't end up taking space on my mom's computer? Any help would be appreciated :)

not sure if it matters but my sister's laptop is a Dell inspiron 15 and her printer is an HP LaserJet M14-M17 and I believe it's connected to the network of her old printer because when I go to the settings it says "XP-320 Series (Network)" and her laptop is running windows 10 home
